Product Description
Filling an automatic burette goes smoothly when you have a reliable hand pump to push liquid up from the reservoir. This red blowball supplies gentle air pressure on demand, so titrant rises into the burette without mouth pipetting or tilting heavy bottles.
This listing is for DURAN catalog number 292450108: Blowball for automatic burettes, with hose attachment and two valves, red. The bulb is made from soft PVC and includes a hose attachment plus two valves that control airflow in one direction. Squeezing the ball pressurizes the reservoir bottle and drives liquid into the burette. It works as a replacement or spare part for automatic burette assemblies and is sold individually. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
Key Features
